Geology of the Transverse Range Province, Southern California

The Transverse Range province of southern California is an elongate geomorphic and structural unit that trends essentially east-west across parts of Santa Barbara, Ventura, Los Angeles, San Bernardino, and Riverside Counties (pl. 4). Its name reflects its transverse orientation with respect to the adjacent provinces, especially the Coast Ranges and Sierra Nevada to the north and the Peninsular Ranges to the south. This distinctive province is geologically very complex, and comprises chains of mountains and hills that are flanked or separated by narrow to moderately broad valleys. These features, as well as most of their structural elements, lie athwart the general northwest-southeast grain of southern California, and several of them are responsible for the anomalous east-west alignment of the coast from Point Conception to the Santa Barbara area, and along the north side of Santa Monica Bay

A MODEL TO EXPLAIN PARTICIPATION IN NEW YORK'S AGRICULTURAL DISTRICTS AND USE-VALUE ASSESSMENT PROGRAMS

Logit regression models are estimated to identify factors affecting decisions to enroll farmland in New York's agricultural districts program and participate in the use-value assessment program. The results suggest that the districts law is consistent with preserving the best farmland at the rural-urban fringe and that the decision to enroll in agricultural districts affects in a recursive fashion the decision to participate in the use-value assessment program. Short-term monetary gains are the overriding considerations in applying for use-value exemptions. This may lead to additional erosion of the tax base via tax preferences for agricultural land.Land Economics/Use,

Towards a method for the economic evaluation of environmental indicators in UK Integrated Arable Farming Systems

Integrated Arable Farming Systems (IAFS), which involve a reduction in the use of off-farm inputs, are attracting considerable research interest in the UK. The objectives of these systems experiments are to compare their financial performance with that from conventional or current farming practices. To date, this comparison has taken little account of any environmental benefits (or disbenefits) of the two systems. The objective of this paper is to review the assessment methodologies available for the analysis of environmental impacts. To illustrate the results of this exercise, the methodology and environmental indicators chosen are then applied to data from one of the LINK - Integrated Farming Systems experimental sites. Data from the Pathhead site in Southern Scotland are used to evaluate the use of invertebrates and nitrate loss as environmental indicators within IAFS. The results suggest that between 1992 and 1995 the biomass of earthworms fell by 28 kg per hectare on the integrated rotation and rose by 31 kg per hectare on the conventional system. This led to environmental costs ranging between £2.24 and £13.44 per hectare for the integrated system and gains of between £2.48 and £14.88 for the conventional system. In terms of nitrate, the integrated system had an estimated loss of £72.21 per hectare in comparison to £149.40 per hectare on the conventional system. Conclusions are drawn about the advantages and disadvantages of this type of analytical framework.

Francis Ellington\u27s use of Prophecy to Explain the Appearance, Deliverance, and Apocalyptic Role of Quakers in the Last Days

Early Quakers rarely relied on ancient or modern (seventeenth century) prophecy to authenticate their faith. The reason for this was their emphasis on inner revelation. After the Nayler episode Quakers slowly began to turn their energies toward making necessary theological and institutional adjustments that would better enable the movement to control the radical individualism of the inner light. One area that has not received much attention is how attitudes toward prophecy were changing. This paper focuses on one distinctive Quaker pamphlet which appeared in 1664. Francis Ellington\u27s A Christian Information Conce��ning These Last Times demonstrates how one Quaker was strugglmg to understand the reasons for the long-delayed consummation of the Lamb\u27s War. In the face of fierce persecution and the difficult conditions for Quakers during the Restoration Ellington searched back beyond Fox for new expressions of prophetic authentication and encouragement. The use of specific prophecy, now seen as coming true, was rare in Quaker writing. Ellington\u27s voice may have been a distinctive one among Quakers of the time but his tendency to incorporate a pacifist element into a militant apocalyptic rhetoric was not unusual in Quaker writing until the 1680s

The development of a high temperature static strain gage system

The objective of this program is to develop electrical resistance strain gages which will permit the measurement of static strains on nickel and cobalt superalloy parts inside gas turbine engines running on a test stand. The specific goal is to develop a complete system able to make strain measurements up to plus or minus 2000 mu strain with a total error of no more than plus or minus 10 percent over a 50 hour period at 1250 K. The initial part of this work consisted of a strain gage alloy development effort in which a variety of alloys were evaluated after being prepared by drop-casting or splat cooling

Integrated Arable Farming Systems and their potential uptake in the UK

Integrated Arable Farming Systems are examined from the perspective of the farmer considering the use of such techniques, and data are presented which suggest that the uptake of the approach may expose the manager to a greater degree of risk. Observations are made about the possible uptake of such systems in the UK and the implications this may have for agricultural and environmental policy in general

End-to-end beam simulations for the new muon G-2 experiment at Fermilab

The aim of the new muon g-2 experiment at Fermilab is to measure the anomalous magnetic moment of the muon with an unprecedented uncertainty of 140 ppb. A beam of positive muons required for the experiment is created by pion decay. Detailed studies of the beam dynamics and spin polarization of the muons are important to predict systematic uncertainties in the experiment. In this paper, we present the results of beam simulations and spin tracking from the pion production target to the muon storage ring. The end-to-end beam simulations are developed in Bmad and include the processes of particle decay, collimation (with accurate representation of all apertures) and spin tracking
